Effect of Yiqi Huoxue (益气活血) Herbs on Vascular Endothelial Cells and Platelets in Patients with Chronic Cor Pulmonale

Objective: To observe the clinical effect of Yiqi Huoxue (益气活血, YQHX) herbs in treating the patients with chronic cor pulmonale and to explore its mechanism by determining the relationship of oxida-tion/antioxidation system and how such herbs change on the function of endothelial cells and platelets. Methods: Fifty-eight patients were divided into two groups: conventional therapy group (control group, 28 patients) and convention plus YQHX herbs group (treated group, 30 patients). The control group received conventional management. The treated group were treated with YQHX 150 ml, twice a day, plus the conventional treatment, and the clinical efficacy was recorded. The lipid peroxidation (LPO), superoxide dismutase (SOD), ot-granule membrane protein (GMP140), partial pressure of arterial oxygen (PaO2), partial pressure of carbon dioxide in artery (PaCO2) and circulating endothelial cells (CEC) were measured respectively before and after treatment, and the relationship between various parameters were analyzed. The results were compared with those of 10 healthy subjects got at the same period. Results: (1) The effective rate and PaO2 of the treated group was higher than that of the control group and there were no difference in PaCO2 between the two groups. (2) The levels of LPO, GMP140, CEC in all the patients before therapy were significantly higher than those of the healthy group, and there were marked decrease in the levels of those after treatment (all P<0. 01). On the contrary, the levels of SOD in all the patients before therapy were markedly lower than those in the healthy subjects and increased after treatment, P<0. 01. (3) The increase of SOD in the treated group was significantly more obvious than that of the control group. In the treated group, the decrease of LPO, GMP140, CEC were markedly more obvious than those in the control group (all P<0. 01). (4) The number of CEC, as well as GMP140, was negatively correlated to PaO2(P<0.01) and SOD (P< 0. 01), which was positively correlated to LPO (P<0. 01). There was a positive correlation between CEC and GMP140 (P<0.05). Conclusion: YQHX herbs in treating chronic cor pulmonale proved to be effective by balancing the oxidation and antioxidation, protecting the pulmonary endothelial cells and activated platelets and helpful in treating respiratory failure.

Diagnostic Value of the Padua Score Combined with Thrombotic Biomarker Tissue Plasminogen Activator Inhibitor-1 (tPAI-1) Detection for the Risk of Deep Vein Thrombosis in Patients with Pulmonary Heart Disease

This study explores the diagnostic value of combining the Padua score with the thrombotic biomarker tissue plasminogen activator inhibitor-1(tPAI-1)for assessing the risk of deep vein thrombosis(DVT)in patients with pulmonary heart disease.These patients often exhibit symptoms similar to venous thrombosis,such as dyspnea and bilateral lower limb swelling,complicating differential diagnosis.The Padua Prediction Score assesses the risk of venous thromboembolism(VTE)in hospitalized patients,while tPAI-1,a key fibrinolytic system inhibitor,indicates a hypercoagulable state.Clinical data from hospitalized patients with cor pulmonale were retrospectively analyzed.ROC curves compared the diagnostic value of the Padua score,tPAI-1 levels,and their combined model for predicting DVT risk.Results showed that tPAI-1 levels were significantly higher in DVT patients compared to non-DVT patients.The Padua score demonstrated a sensitivity of 82.61%and a specificity of 55.26%at a cutoff value of 3.The combined model had a significantly higher AUC than the Padua score alone,indicating better discriminatory ability in diagnosing DVT risk.The combination of the Padua score and tPAI-1 detection significantly improves the accuracy of diagnosing DVT risk in patients with pulmonary heart disease,reducing missed and incorrect diagnoses.This study provides a comprehensive assessment tool for clinicians,enhancing the diagnosis and treatment of patients with cor pulmonale complicated by DVT.Future research should validate these findings in larger samples and explore additional thrombotic biomarkers to optimize the predictive model.

Oxygen affinity and 2,3-diphosphoglycerate level of erythrocytes in patients with cor pulmonale

Arterial blood gases,intraerythrocytic pH (pHi),2,3-diphosphoglycerate,standardP 50 (P 50std) and in vivo P 50 (P 50iv) were determined in 54 patients with cor pulmonale and23 normal subjects.It was found that no significant change of pHi was observed but the differ-ence of pHi and extraerythrocytic pH was decreased.P 50std was significantly decreased whileP 50iv remained essentially unchanged in those cases showing type I respiratory failure.Thesefindings suggest that P 50std cannot accurately reflect the changes of P 50iv in patients of corpulmonale;P 50iv in cases of cor pulmonale usually keeps relatively stable and coincides withthe ‘optimal P 50’,which indicates the adaptation of the organism to chronic hypoxia;and rel-ative intraerythrocytic alkalosis plays an important role in the relief of hypercapnia in cases ofcor pulmonale.

Effect of sequential mechanical ventilation on cardiac function, endothelial injury and oxidative stress response in patients with cor pulmonale

Objective: To study the effect of sequential mechanical ventilation on cardiac function, endothelial injury and oxidative stress response in patients with cor pulmonale (CCP). Methods: Patients with cor pulmonale complicated by respiratory failure who were treated in Dongfeng People's Hospital between May 2014 and February 2017 were selected and randomly divided into the sequential group who received sequential mechanical ventilation combined with conventional therapy and the control group who received invasive positive pressure ventilation combined with conventional therapy. The serum levels of cardiac function-related neurohumoral indicators, endothelial injury indicators and oxidative stress response indicators were detected before treatment as well as 3 d and 7 d after treatment. Results: 3 d and 7 d after treatment, serum NT-proBNP, Copeptin, Ang-II, ALD, ET-1, vWF, sST2 levels of both groups of patients were significantly lower than those before treatment while NO, SOD, GSH-Px and T-AOC levels were significantly higher than those before treatment;serum NT-proBNP, Copeptin, Ang-II, ALD, ET-1, vWF, sST2, NO, 8-iso-PGF2a, MDA, SOD, GSH-Px and T-AOC levels of sequential group 3 d after treatment were not significantly different from those of control group;serum NT-proBNP, Copeptin, Ang-II, ALDET-1, vWF, sST2, 8-iso-PGF2a and MDA levels of sequential group 7 d after treatment were significantly lower than those of control group while NO, SOD, GSH-Px and T-AOC levels were significantly higher than those of control group. Conclusion: Sequential mechanical ventilation for cor pulmonale can improve the cardiac function and reduce the degree of endothelial injury and oxidative stress response.

Magnesium Deficiency in Patients with Cor-pulmonale Caused by COPD

Since 1934,when Hirschfelder first reported magnesium(Mg) deficiency syndrome in man, considerable clinicalworks related to hypomagnesemia have appeared in medicalliterature. Recently, it is considered that Mg is a kind ofnatural antagonist of calcium (Ca). Mg has some effects onthe smooth muscles of the bronchial and pulmonary arteries,and to relax the spasm of them. Therefore, there may exista close relation between Mg and cor pulmonale caused bychronic obstructive pulmonay desease (COPD).
